Is there anyway to see the number of participants and number of observations over time? This would be valuable data regarding the growth of a long-term project and whether various promotional activities have helped recruit more observers and more submissions per week, per month, etc.
whether it’s easy might depend on the project and what exactly you mean by number of participants. if you have say a collection project that is based just on place, then you could probably find observations over time by looking at observation submit date. if you mean number of observers based on the observations submitted, then it’s more or less the same sort of process.
if the project is based on taxon, then submit date is going to be more unreliable because taxon more often changes after submit date. ditto for similar project criteria that are typically added or modified after submittal. the only reliable way to get this sort of thing might be to take snapshots of the counts your looking for at fixed intervals and then combine those numbers later.
if number of participants is based on membership, then that’s harder, too. if there’s a way to see when a user joined the project, then you might be able to use that, but short of that, you’d need to take snapshots, too.
for traditional projects, i don’t think it’s possible for regular users to see the timestamps for when observations where added to projects, if such timestamps even exist. so without those, it’ll be hard to figure out for sure when observations where added to those projects, without taking snapshots.
Hello, Im using the projeto data to take diferente information based on year, like this,
I duplicate the project and change the datas that i want

If you click on the “Usage stats” link for a Traditional project (example), you can see the number of members who joined each month. (This goes for any viewer, not just the project owner, etc.) You can also see the number of observations from each month that are currently in the project. This is based on when the observations were added to iNat, not to the project. Unfortunately, the membership stats don’t seem to be available for Collection projects, even though it could still be useful to see when new members joined the project
You can sort by Date Joined, up or down. I often check for new arrivals.
ok. so then they are keeping track of when people are joining projects (including collection projects). i just took a look, and you can get the underlying data via https://www.inaturalist.org/projects/{project id}/members and https://www.inaturalist.org/projects/{project id}/members.json. so then it’s possible to get the data from there and then aggregate them to whatever time intervals you like.
for example:
